What Causes Numbness and Pain in the Ring Finger?

　　Numbness and pain in the ring finger may result from localized nerve injury, cervical spondylosis, or ulnar nerve palsy.

　　1. Localized nerve injury

　　If the ring finger is accidentally cut, lacerated, or subjected to external compression or infection, the local nerves innervating the ring finger may become damaged—commonly leading to numbness and pain in the ring finger.

　　2. Cervical spondylosis

　　Excessive neck movement, old injuries, local cervical osteophyte formation, or degeneration of cervical intervertebral discs may compress cervical nerve roots, resulting in cervical spondylosis. Patients often experience numbness in the ring finger; other symptoms may include numbness in other areas, dizziness, and neck or shoulder pain.

　　3. Ulnar nerve palsy

　　Compression, fracture, or trauma to the hand may cause ulnar nerve palsy, leading to impaired nerve function in the ring finger and manifesting as numbness and pain.

　　When experiencing numbness and pain in the ring finger, it is advisable to seek prompt medical evaluation to determine the underlying cause and initiate appropriate treatment under a physician’s guidance.
